Simple, they don't do it because it would not work. And you don't have to run down the road just to check your oil level.
The Spyder utilizes is a Dry Sump oil system. Very little oil is kept in the oil pan. This allows engineers to lower the engine by several inches, which is a very good thing. But this requires moving the oil that would normally be stored below the engine to a remote location called the 'Reservoir'. Scavenger pumps maintain the proper oil level in the bottom of the engine and the remining oil is sent to the reservoir.
When you shut the engine off, the scavenger pumps stop and oil can, and usually does, drain from the reservoir back into the bottom of the engine. The dipstick reads the oil level in the reservoir, which may read low after sitting. If you go by this, you will add oil. Then it will read low the next time and you will add more oil. Soon, the oil level is way too high and you have caused yourself grief.
Once the engine is started after sitting, it takes a bit of time for the scavenger pumps to return everything to equilibrium so that an accurate reading can be taken at the reservoir.
But it’s not as bad as you may think. First, the 1330 engine uses virtually no oil at all. Second, if you don’t notice a pool of oil under the bike when you go to ride it, chances are the oil is still where it should be, in the engine. Third, you simply go for a ride. Sooner or later, you’ll need to stop for fuel. That’s when you check your oil level.
Easy, efficient, and very reliable.
Like they say, Work Smarter, Not Harder. Then you can practice the other saying.
Ride More, Worry Less!
